Question

Carbohydrates and lipids are important molecules found in living things.
Part A: Describe how the general structure of a carbohydrate differs from the general structure of a lipid.
Part B: Describe one function that is common to both carbohydrates and lipids.
Part C: A phospholipid is a common type of lipid molecule that is hydrophilic at one end and hydrophobic at the other. Explain how this structural characteristic of a phospholipid contributes to the formation of plasma membranes.
Type your responses to parts A, B, and C in the box below.

Answer 1

Part A) The difference between Carbohydrates (sugars) and Lipids:
1) sugars dissolve in water lipids don't
2) sugars are made-up of sub units that form large polymers and lipids are not and don't form polymers.
3)Lipids store more energy than sugars.
4) sugars form structural components (cellulose in plants) and lipids form boundaries like the cell membrane due to hydrophobic hydrocarbons.

Answer 2

Part B) They both are sources of energy for the cell in a way.

Answer 3

Part C) Phospholipids are amphipathic molecules that make up the bilayer of the plasma membrane and keep the membrane fluid.
